' TRUCK SIDE FRAME.

`Specification of Letters Patent.

Patented June 10, 1913.

Application tiled March 23, 1912. Serial No. 685,809.

T all whom, t may concern Be it known that I, HENRY F. Porn, a citizenof the United States, residing at Cleveland, Cuyahoga county, Ohio, haveinvented an Improvement in Truck Side Frames, of which the following isa specifi cation, reference being had to the accompanying'drawings, inwhich- Figure lis an elevation 'of a portion of.

the side frame embodying m invention; Fig. 2 is a section on-lines II- Iof Fig. l; Fig. 3 is a section on lines III-III of Fig. l showing thebolster in dotted lines; Fig. 4 is a section on lines IV-IV ot Fig. l;nd Fig. 5 is a detail ot the4 bearing mem- My invention relates to truckside frames,

and is specifically directed to providing de' tacha-ble bearings orguides in the bolster window and against which the truck bolster isdesigned to bear.

My improved bearings protect the columns at the sides of the bolsterwindow against wear, and while, in service, they are firmly attached tothe columns, they can readily be removed and replaced when they becomeworn.

Referring to the drawings: 2 isa truck side trame, preferably ofintegral construc- 6, which connects the side frame 2 with the sidetrame at the opposite side of the truck. The bearingmembers 10 areadapted to be secured to the upper parts of the columns 5, which arepreferably slightly recessed, and form bearing surfaces against whichthe sides 11 of the bolster 7 bear between the column guides 8. Thebearing members 10 have bendable lugs 12 and 13 which take about thecolumns 5 and the horizontal flanges-11i on the bottom of thecompression member 4 at the top of the bolster window, and abut at theirlower ends on the offsets 15 of the columns 5. The members 10 protectthe columns 5 against wear and can readily be placed in position bymeans ot the bendable lugs 12` and 13 'which are sledged over the edgesof the columns 5 and the horizontal flanges 14, and the members l() arethus firmly secured to the columns The members 10 can also be easilyremoved in case of Wear by sledging free the bentover .lugsl and 13 'andthus releasing their engagement with the columns 5 and the flanges 14.

It is apparent that there will be a certain amount of wear on the sidesl1 of the bolster 7 between the column guides 8` and bearing members 10,and in such case if the wear has' been mainly on the sides of thebolster, the insertion of new bearing members 10 will not give therequisite tightness .ofi

fit between these parts. VTo provide for this wear I employ a shim plate16 which can be inserted between `one of the bearing members 10 and'itscolumn 5. The plate 16 is held against downward movement by the offset15 ot the column 5 and is clamped firmly to the column 5 by the bcndablemelnber 10. It necessary, in order to compensate for wear, shim plates16 can be inserted between both bearing members l() and the.corresponding columns The holster window is preferably made ofsuflicient cross-scctional arca to admit the bolster into the lowerportion of the window while in horizontal position. It can then beraised vertically, without tilting, to its nor- .mal position betweenthe bearing members 10 with the column guides 8 taking about thelongitudinal sides of' these members 10.

It is obvious that without departing from my invention variousmodifications may be made in my device.

What I claim is:

1. In an integral side frame, an opening therein for the reception of abolster, said:

opening having flanges thereabout, bearing plates positioned in theupper part of said opening and having lugs to clamp vabout said flanges,and being adapted to provide `a bearing surface for the bolster and toprotect the said frame against injury.'

2. In a truck side frame, having therein an opening 'for abolster,columns at the sides of said opening, bearing plates for the bolster inthe upper part of said opening adapted to be detacliably secured to saidframe by bendable means'.

8. In a truck side frame, an opening for a bolster having an venlargedupper portion. and a lower portion of suficient cross-sectional area toadmit the bolster in horizontal position, columns at the sides of saidopening having; recessed'upper portions to provide bearing seats, -andbearing plates adapted to be detachably secured to said I columns onsaid bearing seats by bendable locking means.

4. In a truck side frame, an opening for a bolster havingan enlarged`upper portion,

and a lower portion of suilicient. crosssec bers, a bolster opening'therebetween, and

bearing plates` for the bolster adapted to be clamped to the upperportions of the columns by bendable means.

6. A truck side frame having columns and compression and tensionmembers, a bolster opening therebetween, and bolster bearing platessecured to thecolumns and the compression member by bendabl'e lugs.

17. A truck side frame having columns and compression andtenslonkm'embers, a bolster opening therebetween, and bolster bearingmembers adapted to be clamped to the up- .per portions of said columns,and a plate interposed between one of said columns and one'of saidbearing members. y

8. A bolster bearing member, comprised of a bearing plate, havingbendable attaching ine-ans for attachment to a truck side frame.

9. A bolster bearingA member, comprised of a bearingl plate, having o-nits sides a plurality of bendable lugs adapted for attachment to thecolumns of a truck side frame.
